Effects of different packaging on the quality and ethylene release rate of black plum fruit during cold storage and the subsequent shelf life

Effects of packaging with PE, PVC and microporous membrane packaging on the quality and ethylene release rate of black plum fruit at 0 ℃ and the subsequent shelf life at 25 ℃ were investigated.The experiment results showed that the weight loss rate was inhibited effectively with PE, PVC and microporous membrane packaging ( p < 0.05) which was good for fruit storage.Among these packaging, PVC could most effectively change air condition in package by reducing the volume fraction of O₂ and increasing that of CO₂ ( p < 0.05) .The decline of firmness could be delayed effectively and SSC was kept at a high level.Softening was delayed with PE packaging, and the color change was higher than other plum significantly.Microporous membrane was suitable for fruits that sensitive to CO₂.Ethylene release rate of plums could be inhibited effectively during storage with PE, PVC and microporous membrane packaging, compared with the control without packaging.
